This is one of those stories that you have to read twice, if only because Sam and Josh's banter takes on a different feel when you know what they're talking about...

Especially Sam's line about considering getting one of his own. I admit it's prejudiced by my own opinions in regards to the various women Sam was involved with over the course of the series, but I couldn't help but think, on the second read-through, 'Sam, have you discussed this with Ainsley yet?'.
